Co2+:MgAl2O4 ( Co2+:Spinel) Crystals For Sale
Co2+:MgAl2O4 Single Crystal Substrate Brief Introduction:
Co2+:MgAl2O4 (Co2+:Spinel or Co:MALO) crystals is a new material for passive Q-switching in lasers emitting from 1.2 to 1.6 µm, in particular, for eye-safe 1.54 µm Er:glass laser, but also works at 1.44 µm and 1.34 µm wavelengths. High absorption cross section (3.5 × 10-19cm2) permits Q-switching of Er:glass laser without intracavity focusing both with flash-lamp and diode-laser pumping. Negligible excited-state absorption results in high contrast of Q-switch, i.e. the ratio of initial (small signal) to saturated absorption is higher than 10. Hangzhou Shalom EO offer the high quality Co:Spinel crystals materials with high optical quality and uniform distribution of Co2+ in laser grade polishing and coatings.
